[Python] PyQt6 on Windows : qtquickcontrols2windowsstyleimplplugin.dll: The specified module...

i am trying to test some code using PyQt6. When I try to display en MenuBar in my main.qml, i have this error :

QQmlApplicationEngine failed to load component
file:///C:/Users/[blablabla]/GUIt/main.qml:11:9: Type Menu unavailable
qrc:/qt-project.org/imports/QtQuick/Controls/Windows/Menu.qml:32:15: Type MenuItem unavailable
qrc:/qt-project.org/imports/QtQuick/Controls/Windows/MenuItem.qml:7:1: Impossible de charger la bibliothÞque C:\Users\[blablabla]\Python\Python313\Lib\site-packages\PyQt6\Qt6\qml\QtQuick\Controls\Windows\impl\qtquickcontrols2windowsstyleimplplugin.dllá: Le module spÚcifiÚ est introuvable.


(Sorry i'm french so my errors too, but "Le module spÚcifiÚ est introuvable." means "The specified module could not be found")

I could not find any solved issue similar to my problem so i try my luck here.

I am on Windows 11, and I am using Python3.13.3 (not the native Windows installation)

Here is my code : main.py :

from PyQt6.QtWidgets import QApplication
from PyQt6.QtQml import QQmlApplicationEngine
from backend import Backend

app = QApplication([])
engine = QQmlApplicationEngine()

backend = Backend()
engine.rootContext().setContextProperty("pybackend", backend)

engine.load("main.qml")

if not engine.rootObjects():
import sys
sys.exit(-1)

app.exec()


backend.py :

from PyQt6.QtCore import QObject, pyqtSlot, pyqtProperty, pyqtSignal
from PyQt6.QtWidgets import QFileDialog
from git import Repo
from models.CommitList import CommitListModel

class Backend(QObject):
repoPathChanged = pyqtSignal()
repoNameChanged = pyqtSignal()
commitListChanged = pyqtSignal()

def __init__(self):
super().__init__()
self._commit_list = CommitListModel()
self._repo_path = ""
self.repo = None
self._repo_name = ""

@pyqtProperty(str, notify=repoPathChanged)
def repoPath(self):
return self._repo_path

@pyqtProperty(str, notify=repoNameChanged)
def repoName(self):
return self._repo_name

@pyqtProperty(QObject, notify=commitListChanged)
def commitList(self):
return self._commit_list

@pyqtSlot()
def chooseAndLoadRepo(self):
dialog = QFileDialog()
dialog.setFileMode(QFileDialog.FileMode.Directory)
dialog.setOption(QFileDialog.Option.ShowDirsOnly, True)
if dialog.exec():
selected_dirs = dialog.selectedFiles()
if selected_dirs:
self.loadRepo(selected_dirs[0]) # charge le dossier sélectionné

@pyqtSlot()
def loadRepo(self, path = "C:/Users/lucie/Hesias/B2/MajorProject/major-project-b2"):
try:
self.repo = Repo(path)
self._repo_path = path
self._repo_name = path.split("/")[-1]
self.repoPathChanged.emit()
self.repoNameChanged.emit()
except Exception as e:
print(f"Erreur : {e}")

@pyqtSlot()
def loadCommits(self):
try:
commits = [f"{c.hexsha[:7]}: {c.summary}" for c in self.repo.iter_commits()]
print(commits)
self._commit_list.setCommits(commits)
self.commitListChanged.emit()
except Exception as e:
self._commit_list.setCommits([f"Erreur : {e}"])


models/CommitList.py :

from PyQt6.QtCore import QAbstractListModel, Qt, QModelIndex

class CommitListModel(QAbstractListModel):
def __init__(self, commits=None):
super().__init__()
self._commits = commits or []

def data(self, index, role):
if role == Qt.ItemDataRole.DisplayRole and index.isValid():
return self._commits[index.row()]
return None

def rowCount(self, index):
return len(self._commits)

def setCommits(self, commits):
self.beginResetModel()
self._commits = commits
self.endResetModel()


main.qml :
